Display Card Replacement

[mBox]

One of our Nvidia GeForce 7300GT cards died in a MacPro Dual-Core 3GHz (MacPro1,1). This system needs to feed Dual Cinema 30's.
Any tips on a replacement card? We could hunt down another 7300GT but would rather take the working one out and replace with a single 512.
Problem is finding a complient one.

You could get either the HD3870, or perhaps an 8800 GT. If your work involves a lot of Core Image-based computing, go for the 3870.
